OIL-

SPECIFICATION forming part of Letters Patent No. 293,681, dated February 19, 1884.

' 7 Application filed October 19,1883. (No model.) I i To all whom zit/may concern:

Be it known that I, HERMAN \V. STEM- MERIOH, a citizen of theUnited States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Oil- Cups, of which the following is a specification, reference being had therein tothe accompanying drawings.

'My invention relates to an improvement in oil-cups for lubricating machinery; and it consists in a pendulum operating a plunger that at every vibration opens and closes an oil-conduit, as will be fully described hereinafter.

The accompanying drawings represent my invention. a

Figure 1 is a front view of the cup; Fig. 2, a sectional, and Fig. 8 a plan, view of the same.

A represents a cylindrical cup outwardly threaded at its upper edge, on which the cap B is screwed. From the bottom of the cup projects a tubular shank, a, with a fixed nut, 12,

- and a screw-thread from the nut to the end.

At the outside of the cup, near .its bottom, a curved plate, 0, in the form of an inverted arc, is attached, both ends d'of which are bent forward, and support each a leather cushion, e, fastened to theplate 0. From the center of the arc of the plate 0 protrudes the end of a horizontal shaft, f, to which is rigidly secured a pendulum, P, that oscillates between the cushions e and causes the shaft to vibrate when in motion. The shaft f is journaled in the cup A, and, extending into the interior, carries an oblong block, 9, with a laterallydovetailed groove in its side toward the center of the cup. In the dovetailed groove of the block 9 is held a sliding nut, t, screwed to the end of a wrist-pin, h, on a line with the shaft f. The wrist-pin passes through the slotted head Z of a pitman, k, that, extending toward the bottom of the cup, is there jointed to a plunger, m, which enters the tubular shank a and closes it. The plunger m is cylindrical, but flattened on one side, beginning at' the shoulder a, down to its lower end. The cup A, holding the oil, is firmly to be screwed on a stationary part of the machine or other suitable place overor near the parts to be lubricated, so that the oil, when discharged from the lower end of the shank (it, drops in the place where it is needed. A projection, made for the, purpose, on a moving portion of the machine, placed to periodically come in contact with the lower end of the pendulum, pushes it sidewise against one of the cushions e, and, passing on, releases it,

secured by the wrist pin h, a risin, 3;-and-falling motion is imparted to it, that increases with the distance from the'center. The rising-and-falling motion of the nut z is commu= .nicated to the wrist-pin h and pitman k, caus ing the plunger m to rise or descend each time the pendulum swings from its perpendicular.

When raised, the fiat side of the plunger gives I vent for the, oil to flow down; but when depressed, the end of the plunger above the shoul der it prevents the outflow of the oil by closing the tube.

The slot in the head of the pitman serves to increase or diminish the length of its stroke, I

and by it the height to which the plunger is to be raised, whereby the quantity of oil escaping through the vent is controlled.

Having thus described my invention, I clai m 1. In an oil-cup,-the combination of a pendulum, a shaft which passes through the side of the cup below its top, nut 2', block d, wrist-pin h, pitman k, and plunger m, the parts being combined and arranged to operate substan= tially as shown and described.

' 2. In an oil-cup,the combination of the pend ulum P, shaft f, block 9, and nut i, substantially as set forth.

3. The combination of the nut i, wrist-pin h, pitman' k, and plunger m, arranged and operating substantially as described.

In testimony whereof -I affix my signature in presence of two witnesses.

HERMAN W. STEMMERIOH.
